Sendcloud Shipping: Sendcloud prices and service points at checkout, labels and tracking from the order page1 of 9
What it does
Sendcloud is a multi-carrier shipping platform used across the Netherlands, Belgium, Germany, France, Austria, Italy, Spain and the UK. This add-on adds it to CS-Cart and Multi-Vendor as a shipping carrier with two kinds of delivery: home delivery and service point. It uses the Sendcloud API v3 with your own public and secret key, so prices and carriers follow your Sendcloud account.
How it works
Enter your Sendcloud keys, run the connection test, add a Sendcloud shipping method and choose carriers and price rules. At checkout the customer sees the live price; for service point methods a list and map dialog lets the customer choose a point. On the order, click Create label (or use the bulk action), download PDF, ZPL or PNG, and cancel if needed. Failed requests are retried and visible in the log.
Features
Sendcloud prices at checkout: cheapest or fastest option, carrier filter, exact option, markup, free shipping threshold, fallback rate
Service point picker with list and map, saved with the order and shown on invoices and e-mails
Labels from the order page, automatically at an order status, or in bulk; PDF, ZPL and PNG
Tracking number as a CS-Cart shipment, scheduled tracking and Sendcloud webhook, cancel label, return portal link
Multi-Vendor: one marketplace account or one Sendcloud account per vendor, labels ship from the vendor address
Encrypted keys, job queue with retries, log with filters and CSV export

Sendcloud (API v3) as a CS-Cart real-time shipping carrier: services "home delivery" and "service point"; live prices from your Sendcloud account; cheapest or fastest option, carrier list, exact option code, signature, markup, free-shipping threshold, fallback rate, currency conversion.
Service point picker at checkout (list and map, OpenStreetMap); the point is stored with the order and shown in the admin order, on invoices and in e-mails.
Create the shipment and label from the order page (weight and option overrides), automatically at an order status, or in bulk from the orders list; PDF, ZPL and PNG; ZIP or printer-file download of many labels.
Tracking: core shipment with the tracking number, scheduled tracking check, Sendcloud parcel_status_changed webhook with signature check; cancel a label; return portal link.
Multi-Vendor: marketplace owner mode or one Sendcloud account per vendor; labels ship from the vendor's address.
Connection page with encrypted keys and a connection test, job queue with retries and back-off, cron (command line and secret address), log viewer with CSV export.
Tested on Multi-Vendor 4.17.2. First release.
Does it work with CS-Cart and Multi-Vendor?
Yes. The add-on supports CS-Cart and Multi-Vendor. In Multi-Vendor the marketplace owner can use one Sendcloud account for everyone or let each vendor connect their own.
Which CS-Cart versions are supported?
4.17.2 to 4.21.x.
Where are my credentials stored?
In your own database, encrypted. The key is derived from your store's secret in config.php, so a database dump alone does not reveal them. They are never shown again after saving.
Does it send data to Kavio Labs?
No. The add-on talks to Sendcloud only. The license check sends your domain name to the Kavio Labs license server once a day (Kavio Labs downloads).
What happens when Sendcloud is down?
Jobs fail, wait and are retried automatically (5 minutes up to 12 hours). Nothing is lost and nothing is sent twice.
What happens when the license expires?
New work stops (no new documents, rates, syncs or payments). Work already under way is still finished.
How do I get updates?
Install the new package over the old one. See Installation.
Add a released add-on to this order and save 15% on it. It uses the same edition and store domain.
